IMPROVEMENT- IN STANDING BENCH-VISES.

Specification forming part of Letters Patent No. 210,473, dated December 3, 1878; application tiled October 14, 1878.

To all whom it may concern:

Be it known that I, J. K. B. SOLOMON, of Biegelsville, Warren county, New Jersey, have invented an Improvementin Standing Bench- Vises, of which the following is a specification:

The invention will first be described in connection with the drawing, and thenl pointed out in the claim.

Figure 1 ofthe drawing is a' side view 5 Fig.

2, a vertical section; Figs. o and 4, detail l The movable jaw, B, is connected with the stationary jaw, A, at the lower part by a guidebar, F, that passes through a slot of jaw A and over a roll, G, that greatly diminishes the friction.

The end of bar F has a lug, f', through which passes a screw-bolt, H, held by nuts h', to connect with a chain, I, passing under pulley J and over pulley K to the jaw B, to which it is fastened. The two jaws are .also connected by screw L, that is provided with the ordinary slide-lever M, and works inthe nutsocket N, the latter being kept in place by a collar, a', which enters the recess c of plate C.

O is a guard-bar that passes through large slots in the jaws A B, and is pivoted at o in the movable jaw, resting in a notch, c', of collar a.

The socket N is thus held securely during the rotation of the screw, but may be readily det-ached for replacement or repair by withdrawing the screw, lifting the bar O, andbei ng turned a half revolution. The upper side of the socket N is flattened to correspond with the opposite face of the bar O. i,

Having thus described all that is necessary to a full understanding of my invention, what I cla-iin as new is The bar O,pivoted in jaw B and passing through jaw A, in combination with an independent screw-socket, N, having notched col-y lar a', as and for the purpose described.
